An experiment was conducted to evaluate the application of feeding standard on performances of weaned pigs . The experiment used 24 weaned exotic pigs aged 6 weeks averaged body weight 10 .7 kg for 14 weeks observation. Three different diets i .e . farmers formula (R), commercial diet (K) and standard diet according to NRC recommendation (S) were evaluated . The results showed that S diet on pigs produced better growth rate, feed consumption, feed conversion, cost and profit than other diets and K diet produced better feed conversion than R diet. Carry over effect of the treatments on the growth rate, feed conversion, cost and profit showed that pigs received S diet performed better than those received other diets . But,R diet gave the lowest cost and higher profit than Kdiet. These results concluded that S diet produced the best performance and profitable and produced carry over effect on pigs performances and can be recommended to farmers .

Three hundred day-old male ducklings were allocated randomly into 12 treatment combinations in 3 x 4 factorial design . Three levels of dietary density ration i.e : Low(12% /2,000 kcal), medium (16%/2,500 kcal) and high (20%/3,000 kcal) and 2 breeds of local ducks Tegal (TT) and Mojosari (MM) and their crossbreds (Tegal x Mojosari (TM) and Mojosari x Tegal (MT)) were applied. Each treatment combination consisted of5 replicates, each of 5 birds. The experiment was carried out for 8 weeks and measurements were weekly feed intake, body weight, weight and/or percentage of carcass, internal organs and abdominal fat. Results indicated that no significant interaction was detected between dietary nutrient density and the breeds of ducks on all parameters measured . Breeds of duck, as well as their crosses did not affect growth performance and other parameters . On the other hand, nutrient density influenced growth performance significantly, except for percentage of carcass and internal organs . In general, feed intake, body weight gain, feed efficiency, carcass weight and abdominal fat of ducks fed low density ration were significantly lower than those fed medium density, which were also lower than those fed high nutrient density diet . Weghtand length of intestine and kidney weight, of ducks fed low density diet however, were higher than the two other treatments . Â Keywords : Dietary density ration, breeds of duck, growth

An experiment was conducted to determine the availability of P in defluorinated rock phosphate (DRP) and bone meal (TT) using a slope ratio assay (SRA) technique . Ten different diets were fed to 300 day-old broiler chicks for three weeks. Basal diet (RB) was formulated to contain 0.38% total P. DRP, TT and dicalcium phosphate (DCP) diets were each containing three different levels of total P: 0.45, 0.52 and 0.59%: At the end of the experiment, tibia bones were collected for ash determination. The availability of P was determined by SRA using tibia bone ash as the main parameter. The result indicated that the availability ofP in the DRP and TT were 83 .6 and 91 .3%, respectively . Â Key words : Phosphorus availability, slope ratio assay, broiler

An experiment was conducted to evaluate the effect of supplementation effect of dried and fresh Aloe vera barbadens gels in broiler feed. 180 heads of one âday-old chickens were randomly allocated into 6 treatments, namely : (1) basal ration (BR) + 0,25 g dried gel of Aloe vera (DGAV)/kg ration, (2) BR + 0,50 g DGAV/kg ration, (3) BR + 1,00 g DGAV/kg ration, (4) BR + 25 g fresh gel of Aloe vera (FGAV)/kg ration, (5) BR + 50 g FGAV/kg ration, (6) BR + 100 g FGAV/kg ration. Each treatment was replicated 5 times and consisted of 6 chickens. Feed intake, weight gain, feed conversion ratio (FCR), percentage of carcass and abdominal fats, and mortality were examined. Data were analized by the complete randomized factorial design 2x3, except for data of FCR , which was descriptively analyzed. Result showed that feed intake and weight gain of broilers were not significantly affected by the physical form of A. vera gel. FCR based on live weight and the carcass of chickens feed by DGAV was better than chickens feed by FGAV. Dosses and physical form of A.Vera gel in ration did not significantly (P>0.05) affect the percentage of carcass and abdominal fat, and broilerâs Â mortality, for 5 weeks of observation.
